Chen Ruizhi, Rachelle，I majored in Physical Chemistry at Peking University, with a PhD in Science. I am a senior teacher and retired from the High School Affiliated to Renmin University. I have been teaching CAIE IGCSE and ALevel Chemistry for 20 years and AP Chemistry for 8 years. Education is about discovering and stimulating students' potential, cultivating and shaping their ability to adapt to society.
